In after, the second molten bath portion 35 is then converted to hot melt state, therewith cooling merged with end ring 2.
With reference to Fig. 7, Fig. 7 is the structural representation of rotor.Rotor punching 1 is overrided to form iron core, all rotor punchings 1
Groove 12 be respectively formed a through hole, insertion sky passes through for copper bar 3；After copper bar 3 passes through through hole.Two end ring 3 are installed respectively
At iron core both ends, the both ends of copper bar 3 are respectively installed in a welding groove 21 of both ends end ring 3, the end face 33 of copper bar and end ring 2
The bottom surface 201 of welding groove 21 abuts.
When carrying out the welding job between end ring 2 and copper bar 3, welding groove 21 and copper bar 3 directly obtain high temperature, after hot melt
Condense and mutually merge, the end face of copper bar 3 abuts with the bottom land of welding groove 21 and forms solder side 5.Electron beam device bombardment weldering
Junction 5 makes in the 2 close soldering of copper bar 3 and end ring for mutually compressing state.
And the side face of the corresponding axial location of this solder side 5 phenomena such as uneven surface typically occurs after condensation, therefore need
Increase any surface finish processing work, the surface quality of rotor can be effectively improved.
Referring to Fig. 8, Fig. 8 is the manufacturing flow chart of rotor.With reference to Fig. 1, Fig. 3 and Fig. 7, the manufacture method of rotor
It is as follows：Step S1 is first carried out, multiple rotor punchings 1 are carried out to laminate work, form iron core.Followed by step S2, will be more
Individual copper bar 3 is passed through on iron core by the through hole that multiple grooves 12 are formed on rotor punching 1, and the both ends of copper bar 3 are located at the end face of iron core
In addition.Then step S3 is carried out, two end ring 2 are arranged to the both ends of iron core respectively.
Step S1 completes the combination step of rotor to step S3, followed by the welding step of rotor.
With reference to Fig. 9, Fig. 9 is the welding processing schematic diagram of rotor, and rotary clamp 4 includes mandrel 41, positioned at mandrel 41
The locking nut and support frame at both ends.After step S3 is performed, step S4 is first carried out, rotor is clamped to rotating clip
On tool, i.e. the axis hole 14 of rotor is passed through first by mandrel 41, rotor outside is located at the both ends of mandrel 41 and is provided with outside
Screw thread, screw thread cooperation is carried out by locking nut and mandrel 41, locking nut is abutted on the both sides end face of rotor core, with
Realization is gripped to rotor, and the mandrel 41 for being clamped with rotor is then clamped on to the claw of support frame both sides
On；Now the end face of copper bar 3 closely abuts with the bottom land of welding groove 21 and forms solder side 5, and electron beam device 6 is located at motor
The surface of rotor.
Thereafter step S5 is performed, the space where rotary clamp is subjected to closed and vacuumize process, followed by step
S6, programmable controller or other control system send a control signal to electron beam device 6, electron beam device 6 is moved simultaneously
At solder side 5；Step S7 is then carried out, control system starts electron beam device 6 and sends a control signal to rotating clip
Have and start rotary clamp 4, claw is by motor-driven rotation.After rotary clamp rotates more than a circle, the end face 33 and end of copper bar 3
The bottom surface 201 of ring 2 abuts the weld zone 5 formed and 5 certain expanded range of weld zone is formed ring-type by beam bombardment
Molten bath, the metal in liquid will condense in molten bath, while can be to the arrange parameter or rotary clamp 4 of electron beam device 6
Rotational parameters be adjusted, the velocity of rotation and turnning circle of electric current and accelerating potential, rotary clamp 4 such as electron beam
Deng according to the actual conditions adjusting parameter of the copper bar 3 of rotor and end ring 2, to ensure that the end face of copper bar 3 is integrally welded
In on the bottom surface 201 of end ring 2.
After electron beam device 6 completes welding job, step S8 is finally performed, by rotor from claw and mandrel 41
On remove, and motor center axle is attached on the axis hole of electronics rotor, then rotor is attached in lathe, to solder side
5 position carries out surface rubbing processing.
In the installation method of rotor of the present invention, welding job is bombarded solder side 5 using electron beam device 6,
The general principle of electron beam device 6 is gathered and discharged for electron cloud.When giving the certain energy of electronics, they can depart from
Track transition comes out.Negative electrode is heated by heater elements such as electron tubes so that it discharges and forms free electron cloud, when
When applying certain accelerating potential, electronics will be accelerated, and to anode movement.After electronics is to anode movement, gathered by electromagnetism
Coke installation, form targeted electronic beam.Electron beam weldering carries out ensureing under vacuum conditions bombardment speed and the bombardment of e-book
The degree of accuracy, while reduce the generation of oxidizing slag.
The features such as electron beam has without solder, and hyperbaric heating speed is exceedingly fast, therefore set notch 211 to make end at welding groove 21
Ring 2 and copper bar 3 can directly receive the bombardment of electron beam, improve welding efficiency；And complete side face corresponding to the solder side 5 of welding
On can typically form roughness, it is necessary to carry out surface rubbing processing, and the side of solder-bump 32 set breach 31 can keep away
Exempt from the generation of burr after surface rubbing, reduce by one of deburring operation, and the welding quality of rotor and surface accuracy carry
It is high.
It is copper using vacuum electron beam to being welded between the bottom surface of copper end ring and the end face of copper bar of rotor
Rapidly enter hot melt state therefore prevent weldering Jiao, welding efficiency is high and welding quality is relative improves.
Motor provided by the invention includes motor stator and above-mentioned rotor, in rotor, because rotor rushes
Groove 12 on piece 1 is connected by tooth 11 and sealed, imperforation on iron core side face, and copper bar can be prevented from the rotor in high-speed rotation
In throw away disengaging, improve the security of motor.
Finally it is emphasized that the foregoing is only the preferred embodiments of the present invention, it is not intended to limit the invention, it is right
For those skilled in the art, the present invention can have various change and change, as each dimensional values are only on rotor punching 1
This example demonstrates that more intuitively using, each size can also be according to the multiple proportion between each size and with more on rotor punching
Kind dimension combination；Again or rotary clamp can also use both sides clamping apparatus disk clamping etc. to gripping for rotor, all at this
Within the spirit and principle of invention, any modification, equivalent substitution and improvements done etc., the protection model of the present invention should be included in
Within enclosing.
